The following measurements were made on two individuals (the values recorded remained stable for one hour): Person A: heart rate, 75 bpm; stroke volume, 60 mL Person B: heart rate, 90 bpm; stroke volume, 95 mL Which person has the greater venous return? Which person has the longer ventricular filling time?

A 55-year-old female has an arterial blood pressure reading of 155/95 mm Hg. What are her pulse pressure and mean arterial pressure?

Draw these five graphs on the same set of axes: atrial autorhythmic cell action potential atrial cardiac contractile cell action potential ventricular autorhythmic cell action potential ventricular cardiac contractile cell action potential ventricular myocardial muscle tension

A person’s cardiac output is 7 L/min and mean arterial pressure is 140 mmHg. What is the person’s total peripheral resistance?

What is the relation of Electrocardiogram components with Heart function. Please briefly explain at your own words.

60) If the TV=50 and the ERV = 100 and the IRV = 75 and the RV = 200, what is the VC? Group of answer choices 175 425 150 125 225 61) Referring to the Cardiac Output formula, which value is most important in determining the cardiac output for an individual who is not in good shape? Group of answer choices Heart Rate End-diastolic volume Stroke Volume End-systolic volume 63) Carbon monoxide binds to hemoglobin _____times as strongly as oxygen does. Group of answer choices 25 200 50 100 2 64) When exercising, Starling’s Law comes into effect. Constantly contracting muscles will increase the venous return to the heart. Which of the following will be true in this case? Group of answer choices Local constriction of precapillary sphincters that control blood flow to the exercising muscle Decrease in Heart Rate Dilation of blood vessels that go to the digestive organs Decrease in the diameter of blood vessels to the exercising muscles Increase in…
